Merging with Merge Plugins mod (easy question I think?)

[gheedorah]

I'm diving into Merge Plugins, and the first thing I want to do is NOT included/explained in the GP tutorial I'm using. There's a patch in the Pre PaMa installer, it's only one tiny change to an actor, but it's taking up a plugin spot as an ESP. It's info says to load directly after the Thief module, or to merge it into the Thief module. So that's what I'm trying to do. I've checked STEP, and the comments on the GP video, and the forum thread for the mod itself, and googled, but because of the Merge Plugins title, most of what I get are questions/posts/results about TES5 or Mator or Wrye Bash or whatever else.

 

Anyway, the GP tutorial shows the steps to merge a bunch of existing ESPs to create a new ESP. What I need to do is to merge the record from one ESP into an existing ESP. I cannot find a tutorial for this (seemingly simple) task anywhere. I'm a touch frustrated, and I'm sure this is a stupidly obvious question/answer, but I don't want to make (uneducated) guesses about how to use this software, especially on my first time through.

 

I'm super grateful for any help here.
